FFmpeg is experiencing an error while segmenting MP4 videos, which can be frustrating for users who rely on this tool for video processing. This issue affects individuals and organizations that use FFMPEG to break down large video files into smaller segments.

The error message indicates a problem with the segment command, making it difficult to complete the task efficiently. In this guide, we will explore the root causes of this issue and provide step-by-step solutions to resolve the problem.

⚠️ Common Causes

  • One possible reason for this error is that the `-segment_time` option is set too low. When the segment time is too short, FFMPEG may not be able to process the video correctly, resulting in an error. To fix this issue, try increasing the segment time to a reasonable value, such as 10 or 30 seconds.
  • Another possible reason for this error is that the `-segment_start_number` option is set too low. When the segment start number is too low, FFMPEG may not be able to find the correct starting point for each segment, resulting in an error. To fix this issue, try increasing the segment start number to a reasonable value, such as 1 or 5.

🔧 Proven Troubleshooting Steps

Increasing Segment Time

  1. Step 1: Open the FFMPEG command prompt and update the `-segment_time` option to a higher value. For example: `ffmpeg -i F:\video_data_set\non-profit-in-funnel-scripts.mp4 -f segment -segment_time 30 -segment_start_number 1 -codec copy -copyts -avoid_negative_ts 1 F:\video_data_set\test\%d_4k_compressed.mp4`
  2. Step 2: Save the updated command and run it to test if the error is resolved.
  3. Step 3: If the issue persists, try increasing the segment time further or exploring other options.

Increasing Segment Start Number

  1. Step 1: Open the FFMPEG command prompt and update the `-segment_start_number` option to a higher value. For example: `ffmpeg -i F:\video_data_set\non-profit-in-funnel-scripts.mp4 -f segment -segment_time 5 -segment_start_number 10 -codec copy -copyts -avoid_negative_ts 1 F:\video_data_set\test\%d_4k_compressed.mp4`
  2. Step 2: Save the updated command and run it to test if the error is resolved.
  3. Step 3: If the issue persists, try increasing the segment start number further or exploring other options.

🎯 Final Words

To resolve the FFMPEG error during segmenting MP4 videos, try increasing the segment time or segment start number. If the issue persists, explore other options such as adjusting the codec settings or using alternative video processing tools. By following these steps, you should be able to successfully segment your MP4 videos without encountering any errors.
